It paints on like water - use twice a day.
I have been hypothyroid for seven years and am now on T3 & T4, but would second Stitchnripper's recommendation for Prostrong. I use the strengthener, the calcium treatment and the moisturiser once a day. For the first time in my life I no longer have peeling and flaking. It only takes a couple of minutes a day, but kept up, I've found it really works.
